its not like that if u create only single blog also just write original articles and informative content on that ... you can also make a single blog and write daily good posts on that no need to create several blogs and then also if u want to create different niche blogs then make min 50 blogs per months so that earning will comes from different blogs and location ...
It depends on your as long as you can manage those specially in maintaining post and link building. The more blogs, the hard to maintain.
You put together as many blogs as you like as long as you are able to maintain them all. Blogs are easy to set up, but can be very difficult to maintain. They need constant updating and organizing. If you're thinking of putting a lot of information up that is not necessarily 'news-like' in format, it might be better to create a number of websites instead. Good luck.
You can create as much blogs as you like I know people who have blog networks of niche sites of like 300-400 blogs
depends... you can have 150 blogs but with 50 visitors daily and with 0 page ranks. And you can have 1 or 2 blogs with a good traffic and a good page rank. This second option is better. So no quantity !!! Quality rules!!!
100 blogs? that will need more then just one administrator... are you going for 100 blogs generating 1$ each a day rule? that's going to be very hard to achieve on your own
You can have as many as you wanted. As long as those blogs are comply with Google Adsense TOS then you have nothing to worry about. However, I would recommend you hire some administrator to keep those blogs secure. I had seen many webmasters manage his 100 blogs by himself alone. One day he found his site ranking down and some banned. His blogs has being penetrated by iFrame malware and he did not aware of it until they are collapsed.
There is no limit in place for the amount of sites you can create to put Adsense on, but I would suggest going the other way actually and make a few really successful blogs opposed to hundreds of decent blogs.
Thank u very much to everyone for good suggestion. Yes it is difficult to manage many blogs but few blogs with good article and quality post will bring more visitors and revenue.
There are no rule or limitation to use. you can create 100 even thousand or more if you can maintain but IMO create 2-3 quality blog instead of 100's of blog .
From what i learned, you can use a single adsense account for multiple blogs or website. so it is UNLIMITED.
